Remarks. — The above genera were first discovered and described 

 by myself, but I failed then to note the distinction between the two. 

 I have now thrown all the prior and new species together. These 

 singular birds are peculiar to the mountains, and dwell in moist 

 woods where there is plenty of underwood ; they are solitary, silent, 

 live and breed on the ground, and feed on seeds, gravel and insects ; 

 their stomach is thick — almost a gizzard. They should stand with 

 Aipunemia and Brachypterix, between Pitta and Cinclus. Our Horor- 

 nis and Monticola are analogous forms among the SylviancB, and Todus 

 among the Muscicaps. Gould has figured our first species of Tęsia, 

 which he calls Micrura squamata.

Dimorpha, mihi (see ' Indian Review,' Siphia). 



Bill short, cylindrico-depressed ; Muscicapan, but less vvide and 

 less armed at the tip ; base loaded with a forward soft zone, putting 

 forth hairs which partly conceal the nares ; rietus less wide and less 

 armed than in Muscicapa, but approaching thereto ; wings more or 

 less elongated and acuminated, with 4th, 5th, or 6th ąuill longest; 

 the first thręe or four more regularly gradated than in Muscicapa ;
